Why can’t I change the clan profile in Clash of Clans?

From October 8, 2022 to November 1, 2022, the national server official temporarily closed this function. The general content of the closure announcement is that technical upgrades will be carried out from now until October 30, 2022. During the upgrade period, personal nicknames, tribe nicknames, and tribe descriptions will not be modified, and other game functions can be used normally.
